     The PowerCube

AudioGraph PowerCube  

It is not only producing high quality, unique 3D-measurements of amplifiers, it is also an integrated part of the development and production cycle at the world leading audio manufacturers.

The PowerCube Measuring System
Our PowerCube Stand Alone System allows you to test all your new audio amplifier constructions, conventional or Class D.
Do you think Class D is the solution for stability? You'd better check it before you go into production! For several decades it has been common knowledge that a loudspeaker is all but an 8 ohm resistor. Playing an 8 ohm speaker may hit the amplifier with impedances as low as 2 ohms, and with severe phase shifts as well - both capacitive and inductive.

  Power Cube Option:

     Water Cooled Load Box

The PowerCube Option - Water Cooled Load Box is an option for very high power measurements according to CEA2006. The system uses the concept of electronic loads to simulate reactive loads and can thus measure very large amplifiers.

"What Is A PowerCube?"
"A PowerCube is a unique piece of test equipment that measures an amplifier's output voltage across 20 impedances from 1 to 8 ohms. Developed by AudioGraph, the PowerCube adheres strictly to the IHF 202 signal standard to create informative three-dimensional (3D) graphs of voltage versus impedance and phase at a single frequency, typically 1 kHz."
(excerpt from The Clarion Product Training Manual)
